I am using the Avada child theme + LiteSpeed Caching plugin.

In LiteSpeed Cache Page Optimization in CSS Settings I checked

• CSS Minify – OFF
• CSS Combine – ON
• Generate UCSS – ON
• UCSS Inline – OFF
• CSS Combine External and Inline – ON
• Load CSS Asynchronously – OFF

After that, appearing mobile menu issue, showing the only list of menu items, it’s not hidden, and with no click, no icon.

I added to [7]Tuning > CSS Excludes:

.fusion-tb-header
.avada-menu-mobile-menu-trigger
#menu-gl-mobile-main-menu
#menu-gl-single-page-main-menu
.fusion-menu-element-wrapper
.fusion-menu-element-list

The Google PageSpeed now for mobile is extremely good, over 90%, but have issue with mobile menu.

Now show the icon with box, but when click noting happened. What is the problem? Any help? Thanks
